UNITED STATES WILLIAM J. ACKERMAN, OF GRAND RAPIDS, MIOHlGAN.

BED-SLAT FASTENER.

$PECIFICATION forming part of Letters Patent No. 340,651, dated April 27, 1886.

Application filed February 23, 1886.

To aZZ whom it may concern:

Be it known that I, WILLIAM J. ACKERMAN, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Fastenings for Bed- Slats; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and fig ures of reference marked thereon,whieh form a part of this specification.

Figure 1 is a perspective view of side rail, showing slat-plate. Fig. 2 is a perspective view of portion of slat and of my fastening. Fig. 3 is a top view of slat and rail when fastened together. Fig. 4 is a sectional view on the line no a: of Fig. 3.

Similar letters refer to similar parts.

The object of my invention is to furnish a fastening adapted to hold together the side rails of a bedstead and to prevent any spreading thereof.

I describe my invention as follows: Upon the under side of and near each end of a bedslat, B, I fasten, by means of the screw f, the metal disk D, said screw being countersunk therein and permitting a revolving motion of said disk, which is provided with a projecting semicircular ing, 0, extending about one-third Serial No. 192,910. (No modeLl its outer circumference, having the flange (I. Said disk is also provided with the fingerpost 6, by which the disk is turned. Upon the side rail A is fastened the plate 0, having the inward-projecting flange a and the slot 1), the side rail being cut away behind said plate to permit the entrance of the ing a. It will be seen that, the slat being placed in position upon the side rail, the lug 0 may be thrown around in the slot 1), the flange d passing under the flange a, forming a lock.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a bed-slat fastening, the disk D, turning on the countersunk screw f, and having a semicircular lug, 0, with flange d thereon, and the finger-post c, in combination with a looking side plate, as shown and described.

2. In a bedslat fastening, the disk D, turning on the countersunk screw f, and having a semicircular lug, c,witl1 flange (l thereon, having also the finger-post e, in combination with the side plate, 0, having the slot b and flange a, substantially as shown and described.

In testimony whereof I affix mysiguatu re in presence of two witnesses.

WM. J. ACKERMAN.
